Lime in glass – a vital component

Lime and limestone are essential components in glassmaking. When lime is heated with silica sand (SiO2) and sodium carbonate (Na2CO3), a solution is formed that does not crystallize when cooled. Instead, it hardens to an amorphous, clear and nearly colourless solid - namely, glass. A range of chemical limestone and lime product types are available for general applications and achieving various properties such as; flux capture, managing viscosity, improving durability and chemical resistance.

Limestone is composed of the mineral calcite (calcium carbonate) and/or the mineral dolomite (calcium and magnesium carbonate) along with small amounts of other minerals.
